Graphs
Graphs are visual representations of data that help illustrate amounts and relationships. There are several common types of graphs, including pictographs, pie charts, map charts, histograms, bar graphs, and line graphs. Each graph type has distinct features - for example, pictographs use icons to represent quantities, pie charts show data as percentages, and line graphs connect data points with lines. Graphs are useful tools for understanding and analyzing various sets of information.
